Liyun Jiang, Xin Ma, Shuangshaung Zhao, Yanyan Tang, Fengxia Liu, Ping Gu, Yongcai Fu, Zuofeng Zhu, Hongwei Cai, Chuanqing Sun, Lubin Tan (2019). Next steps: We aim to elucidate the SNB-involved regulating pathway(s) for seed shattering and seed size and explore genetic manipulation in the SNB gene to enhance rice grain yield in the future. We introduced the mutated allele into a current high-yielding cultivar and observed a positive effect on grain weight in progenies harboring the mutated allele, showing that the new mutated allele has potential in rice breeding applications. appointed as Minister for Justice, Equality and Defence in March 2011. The Department of Justice and Law Reform became the Department of Justice and Equality (with effect from April 2011), with Alan Shatter T.D. Interestingly, the loss-of shattering mutant had larger seeds and a higher grain weight than wild type. Examples of Shatter in a sentence Alan Shatter, T.D., Minister for Justice, Equality and Defence reports on work done during first 12 months of Government. We found that SNB positively regulates the expression of two genes, qSH1 and SH5, known to modulate seed shattering, and also suppresses lignin deposition in the abscission zone. We determined that a single nucleotide change in SUPERNUMERARY BRACT ( SNB), encoding a plant-specific APETALA2-like transcription factor regulating the development of floral organs, caused the transition from easy shattering in the wild type to no shattering in the mutant. At the same time, we tested whether the mutation of a seed shattering gene can be applied for rice breeding to improve grain yield.įindings: We identified a loss-of-shattering mutant, named suppression of shattering 1 ( ssh1), through a screen of mutagenized wild rice introgression lines with naturally high shattering.
Question: We wanted to know whether other genes participate in rice seed shattering.

Thus concludes our slang archive for Shatter. In recent years, several key genetic factors regulating seed shattering have been identified in crops, and the selection of desirable mutations has promoted crop domestication and improvement by reducing shattering. Submit a new or better definition for Shatter. By contrast, non-shattering varieties have incomplete abscission layers or lack the abscission layer altogether. In general, easy-shattering varieties form a complete abscission layer. Previous studies have shown that seed shattering is determined by the development of the abscission layer, which is located at the junction of the seed base and the pedicel. In domesticated crops, however, the reduction of shatter is a desirable trait, as keeping the seeds on their mother plants facilitates efficient harvesting and prevents yield loss. īackground: ‘Seed shatter’ refers to the release of mature seeds from their mother plants, which allows offspring dispersal in the natural environment. identified a genetic factor regulating seed shattering in rice.
